【摘要】 通过对中国大陆 7级以上地震震前 1年 5级地震的活跃、平静和固体潮调制触发的空间分布特征以及中国大陆强地震震源机制空间分布特征的分析和讨论 ,初步认为西昆仑 -阿尼玛卿等断裂组成的第二弧型带是中国大陆十分重要的 7级以上地震活动特征的分界带 ,它不仅是 7级地震前 5级地震呈现平静和活跃地区的分界带 ,也是固体潮调制和非调制 7级地震的空间分布分界带。这可能同中国大陆强震震源机制解的空间分布特征有关。更多还原

【Abstract】 The active and quiet phenomenon a year before the moderately strong earthquakes with M_ S≥7.0,spatial distribution characteristics for the solid tide modulating and triggering earthquake and strong earthquake mechanism on the Chinese Continent has been studied.It is considered that the west Kunlun-A’nymaqn second arc fault zone is a very important boundary zone.It is not only a boundary zone for the moderately strong earthquake active and quiet pheonomenon one year before the strong earthquakes with M_ S≥7.0,but also is the spatial distribution zone of the solid tide modulating and non-modulating strong earthquakes ( M _S≥7.0).It could relate to the spatial distribution of focal mechanism.Focal-mechanism solution of the strong earthquake might be related with the characteristics of spatial distribution in this boundary zone on the Chinese Continent.更多还原
